irregular whitish linear mine, not associated with leaf margin (Spencer,
1976: 383 (fig. 666)).
lower-surface at first, upper-surface later. The upper part is 7-10
cm long and no more than 2 mm wide in the end. Frass in thick, black
frains, sometimes in pearl chains. Pupation outside the mine, exit
slit either in upper or in lower epidermis (Bladmineerders van Europa).
Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.
The larva is described by Griffiths (1973c),
Hering (1955a, as nilssoni),
de Meijere (1937) and illustrated in Bladmineerders van Europa. Posterior spiracles each with 24-28 bulbs (Spencer,
1976: 383 (fig. 669)).
The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).
Robbins (1989 and 1991: 66) recorded mines of Phytomyza archangelicae
on Angelica and Angelica sylvestris. Pitkin & Plant, following Robbins, also recorded mines on Angeliaca sylvestris.
Henshaw in Chandler,

Hosts in Great Britain & Ireland:
of year - mines:
June and August (Hering, 1957).
of year - adults: Currently unknown.
in Great Britain & Ireland: Robbins (1989
and 1991: 66) recorded
mines of Phytomyza archangelicae from Warwicks, but Henshaw
in Chandler, 1998: 139 says
that confirmation of its British status is required.
Distribution elsewhere: Widespread in continental Europe including North Germany, Sweden,
the Faroe Is. (Spencer, 1976:
383), The Netherlands (Bladmineerders van Europa), Lithuania and Poland (Martinez in Fauna Europaea).
